You want to do all that, then still can prove the picture is authentic. The editing history show what had been changed compare to the previous version, from the color adjustment to blur areas... it's not about preventing editing, it's about proving the authenticity when needed.

Reporters who only capture pictures on an iPhone and not a "real" camera, and who also never need to edit the photo to crop off or obscure identifying information, innocent bystanders/victims, gory violence or nudity, etc...

So, 90% of photojournalism outside of the major cities, then.

you could do edits like crops in a way that preserves the signature using ZK proofs
